I have 6 hens, 2 of which are bantoms. A week ago the 2 bantoms went broody so we bought them some fertilized eggs to sit on. Everything was fine until today. One of the bantoms has a watery eye and it's closed most of the time. When I looked closer I could see tiny little things crawling around her eye. I don't know if they are lice, mites, worms or something else. They are tiny, about 2-3 mm long in size, thin and white in colour. They DON'T have a head, wings or legs and look more like a thin worm.
I cleaned out the chicken shed (even though I only did it a week ago), then I covered all the chickens with derris dust and I also bathed the bantoms eye with some saline solution and I'm wondering what else I can do ?
I'm worried she may go blind.
Thanks in advance
